In pictures: The Queen visits the Game of Thrones set in Belfast

There could have been few stronger validations of that theme than the sight of
Her Majesty and the Duke of Edinburgh alongside First Minister Peter
Robinson and Deputy First Minister Martin McGuinness in the corridors of the
19th Century building. Sinn Fein veteran and former IRA commander Mr
McGuinness was held in the prison for over a month in 1976 on a charge of
IRA membership - a count that was later dropped in court. Democratic
Unionist leader Mr Robinson was detained on a number of occasions during the
1980s for his involvement in protests against the controversial Anglo Irish
Agreement.
